Comparing E319 - Tertiary-butylhydroquinone (tbhq) vs E479B - Thermally oxidised soya bean oil interacted with mono- and diglycerides of fatty acids

What is tbhq in food?

TBHQ (E319) is a synthetic antioxidant added to fats and oils to slow oxidation, helping prevent rancidity, off-flavors, and color loss in foods.

Is tbhq bad for you?

At the low levels allowed in foods, it’s considered safe by regulators; adverse effects have been observed only at much higher doses in animal studies, with an ADI of 0–0.7 mg/kg body weight/day.

What foods contain tbhq?

It’s commonly used in vegetable oils and fat-rich processed foods such as snacks (chips, crackers), instant noodles, microwave popcorn, baked goods, and some fast‑food frying oils.

How much tbhq is harmful?

The acceptable daily intake is 0–0.7 mg per kg body weight per day (about 50 mg/day for a 70‑kg adult); regulations typically cap TBHQ at 200 mg/kg (0.02%) of the fat or oil, and adverse effects are linked to doses far above these levels.
